" So if European leaders want to tell me that 2 ppm increase in a
trace gas ( that is 2 parts per million) is worth destroying mans
advance in lifestyle, (etc.) "

The CO2 global level in the early 1800s is put at around 280 ppmv, and
most researchers regard that (based on ice core studies) as having
been a stable figure for many centuries (millennia?) beforehand -
though of course a great distance back in time, much higher levels of
CO2 have been described.

In 1958, the start of the Mauna Loa record, the figure is ~315 ppmv
(parts per million by volume).

In 2000, the figure is ~367 ppmv

Latest figure is ~385 ppmv.

I make that an increase from roughly 'pre-industrial' of 105 ppmv
(+37%), and within the internally consistent Mauna Loa record, an
increase of (385-315 =) 70 ppmv, or ~22% over the past half-century.
Or have I mis-interpreted the original article?

Martin.

You interpreted Joe's article correctly. It appears that, shockingly,
Joe either completely made something up or made a large error.

Seems to fit the pattern of his previous article where he said the warming
of the air followed the change to a warmer PDO whereas it was the other way
round.
